Abstract

A display device is provided. The display device includes: a substrate including a display area including pixels at which an image is displayed and a peripheral area at which the image is not displayed, the peripheral area disposed outside the display area. In the peripheral area, the display device further includes: a plurality of thin film transistors connected to the pixels and with which operation of the pixels is tested, the thin film transistors including gate electrodes arranged separated from each other on the substrate; and a bridge wiring electrically connecting adjacent gate electrodes of the plurality of thin film transistors to each other.

Description

[0001]This application claims priority to Korean Patent Application No. 10-2017-0104143, filed on Aug. 17, 2017, and all the benefits accruing therefrom under 35 U.S.C. § 119, the content of which in its entirety is herein incorporated by reference.BACKGROUND1. Field[0002]One or more embodiments relate to a display device, and more particularly, to a display device which may minimize occurrence of defect in a circuit during a manufacturing process.2. Description of the Related Art[0003]Generally, a display device includes a display area, and plural pixels are arranged inside the display area. When defect occurs in a circuit of the display device, the quality of an image produced at the pixels by the display device may deteriorate. Therefore, minimizing occurrence of a defect in a circuit or minimizing a defect occurrence rate of a circuit during a manufacturing process is desired.[0004]However, in the case of a display device and manufacturing method thereof according to a related a...
